I have a 90x156 piece of taffeta en route that I'd like to try using as a two person hammock-couch in my TV room. I'm planning to hang it parallel to the wall with the TV so we can recline perpendicular in the hammock and watch TV. I'm thinking of pulling the "back" corners shorter before whipping to create a trapezoid /==\ in hopes of achieving the right back support.
Any thoughts? Has anyone tried anything similar?
